Description

Benzoyl Fluoride, 4-Chloro-2-Methyl- (9Ci) is a specialized organofluorine building block characterized by its reactive benzoyl fluoride and chloro-methyl substituted aromatic ring. This compound matters for its role as a key intermediate in the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research where the introduction of fluorine atoms is crucial for modulating biological activity and stability. It is needed by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and advanced material sectors for constructing novel compounds.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring fluorinated aromatic motifs.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and pesticides where the 4-chloro-2-methyl substitution pattern is biologically relevant.
• Liquid Crystal & OLED Material Research: Acts as a building block for fluorinated organic semiconductors and liquid crystal compounds.
• Polymer Chemistry: Employed in the creation of specialty polymers and coatings with enhanced chemical resistance.
• Cross-Coupling Reactions: The benzoyl fluoride group can be utilized in transition metal-catalyzed reactions for carbon-carbon bond formation.
• Fluorination Reagent Precursor: Can be used to generate other fluorinating agents or to introduce the benzoyl group into target molecules.

Quality Control

Our Benzoyl Fluoride, 4-Chloro-2-Methyl- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, GC, NMR, and FTIR to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request. We adhere to cGMP standards where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
